CORPORATION OF MASSACHUSETTS,

CONVEYER non DRIERS.

Application filed April 8, 1916.

T 0 all whom it may concern:

Be it known that I, FREDERICK G. Sanonn'r, a citizen of the United States, residing at VVestford, in the county of Middlesex and State of Massachusetts, have in.- vented a new and useful Conveyor for Driers, of which the following is a SPBClfiCatIOIL This invention relates to a device for com veying wool or other stock along a drying. machine. I

The principal objects of the invention are to provide a simple mechanism by Which the wool will be moved along by means of a U simple reciprocating motion, and to construct it in such a way that there will be no tendency to move the stock in the wrong direction.

The invention also involves improve, ments in details of construction as will ap pear.

Reference is to be had to the accompanying drawings in which- Figure l is a plan of the inside of a wool drier showing one form of this nvention applied thereto; Fig. 2 is a side elevation of the working parts thereof; Fig. 3 is a. similar View of a portion of the mechanism on enlarged scale; Fig. 4 is a view similar to Fig. 2 showing modifications, and Fig. 5 is a similar view showing another modification.

The invention is shown as applied to a. drier having a casing 10 of well-known type in which the wool is delivered to and supported on a slatted stock support 11, the slats of which run longitudinally so as to provide longitudinal openings therethrough. In the form shown in the first three figures this stock support reciprocates. Underneath it are shown transverse shafts 12 journaled in stationary bearings. On each of these shafts are fixed a series of arms 13. On each arm is located a stock pushing device 14 shown in the form of a metal, wood or other plate having saw-teeth on its upper edge projecting forwardly in the direction in which the material is to be conveyed. On the shaft also are located a pair of radial pins 15 at the ends. Loosely journaled on this shaft are a pair of disks 16 each one having a pin 17 adapted to move in apath intersecting the path of a pin 15. Projecting upwardly from the disk is an arm 18 having a counterweight 19 thereon. It will be un- Specification of 13etters Patent.

derstoodthat these parts can be located at one or both ends of each shaft. In this form of the invention the support 11 is reciprocated by means of a shaft 20 having a crank arm 21 thereon connected with the table by links 22. Movable with the support 11 are two sets of pins 23 and 24.

As the support 11 moves back to the end j to swing downwardly through the slats away,

from the stock. This of course occurs just before the stroke is completed in that direction and the counter-weight 19 then remains in that position during the forward stroke. This causes the wool to be advanced with the stock support 11. It will be seen that there is no chance on the forward motion of the stock being retarded in any way by the pushers 14 because they are withdrawn out of contact with it at that time. Projections 26 on the disks engage a pin 27 to limit the motion of the disk in both directions. When the stroke in this direction is about to becompleted the other pins 24 come in contact with the arms 18 and swing them in the other direction, which causes the shafts 12 to turn back and the members 14 to move up between the slats. Then the motion in the other direction is commenced with the stock on the support. The stock therefore is held from moving backward with the support.

In the form of the invention shown in Fig. 4 some modifications are made. In this case the stock support 31 is shown stationary and slanting toward the discharge end, but the shafts 32 are mounted on a frame 33, which is reciprocated by any desired mechanism. The shafts 32 are provided wit-hthe same devices as the shafts 12 in the other form except that in this case the stock pushing devices 34 are shown in the form of pins. The operation is similar to that of the form shown in the other figures. In this case the support being stationary the stock is carried directly forward by the forward motion of the frame 33. It is at the end of the rearward motion of this frame that the pins 34 are projected up between the slats and at the end of the forward motion that they are retracted.

In the form shown in Fig. 5 the table 11 reciprocates, while the retaining teeth 44: are stationary. They are fastened to girts 45 under the table. They have such a slant on one side that the stock is carried over them by the table on its forward motion, but is "retained by their upright edges on the backward motion of the table. Thus no moving parts are required except the table.

Although I have shown and described only three forms in which the invention can be carried out I am aware of the fact that it can be constructed in many other forms without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to any of' the forms shown or to the details of construction shown and described, but

What I do claim is 1. In a drier, the combination of a'slotted support for the stock, aplurality-of parallel cross bars movable relatively to the support and located under it, independent teeth individually fixed to each of said bars and projecting up through the support, and means located atthe end of the support for causing a relative back and forth-motion between the bars and support.

2. In a drier, the combination of a slatted stock support, a transverse shaft, a series of arms fixed on said shaft, said arms having stock-pushing means fixed thereon, means for causing a relative reciprocation between Copies of this patent may be obtained for the support and shaft, and means whereby upon relative motion between the shaft and the support to the end of thejstroke, said stock-pushing means and their arms will be raised.

3. In a drier, the combination of a slatted stock support, a transverse shaft located under the same, an arm pivoted on said shaft and having a counter-weight thereon, a series of arms fixed on said shaft, said arms having a stock-pushing means thereon, means whereby upon relative motion between the shaft and the support, the arm having the counter-weight will be pushed over at the end of said motion, and means whereby upon the motion of the arm in that direction said stock pushing means and their arms will be raised.

4. In a stock conveyer for a drier, the combination of a relatively reciprocable slatted support and transverse shaft, a disk pivotally mounted on said shaft and havin an arm projecting therefrom provided with a counter-Weight, a pin on said disk, an arm projecting from the shaft adapted to be en gaged by said pin to turn the shaft with the disk in one direction, a series of arms projecting from the shaft, and stock-pushing means mounted'on said arms and adapted to be projected up through the slatted support When the shaft turns.

In testimony whereof I have hereunto set five cents each, by addressing the Commissioner of Patents, Washington, D. O.
